malware_signature_advanced
High7.0–8.9 · A05 Security Misconfiguration · CWE-200DetectedConfirmed fixWhere / evidence: Unusually long base64 blob (>200 chars) detected — possible payload injection
Impact: Publicly reachable resource that should not be exposed.
Why it matters: These patterns are strongly associated with compromised servers. An attacker may have placed a backdoor allowing arbitrary command execution, data theft, or further propagation.
AI Recommended Fix:- Immediately take the site offline or into maintenance mode.
- Compare all PHP files against a known-good backup or clean CMS download.
- Delete any unexpected files, especially in writable directories (uploads, tmp, cache).
- Rotate all credentials: database, FTP/SSH, CMS admin, API keys.
- Scan with a server-side malware scanner (e.g. Maldet, ClamAV, Wordfence CLI).
- Harden file permissions: web-accessible directories must not be world-writable.
- Report to your hosting provider and consider engaging an incident-response service.
# bash
find /var/www -name '*.php' -newer /tmp/ref_date -ls # find recently modified PHP
find /var/www/uploads -name '*.php' -delete # remove PHP from uploads

Resolved IP listed on 1 blocklist(s)
High7.0–8.9 · A08 Software & Data Integrity Failures · CWE-506DetectedResearched · citedWhere / evidence: IP 104.21.57.221 listed on: zen.spamhaus.org.
Impact: A blocklisted IP harms email deliverability and may indicate prior abuse/compromise.
Why it matters: An IP listed on Spamhaus ZEN matters because ZEN is a combined DNSBL used for email filtering, so listed sending IPs can be rejected or degraded by receivers until the underlying abuse condition is fixed and the listing is cleared[1][2]. For this finding, the authoritative remediation is to identify the specific Spamhaus zone and follow Spamhaus’s own resolution steps, then request removal after correcting the root cause[1][2][4].
1. Confirm the exact Spamhaus listing and scope using Spamhaus’s IP and Domain Reputation Checker or the IP removal flow, because ZEN is a combined list and the res
AI Recommended Fix:- An IP listed on Spamhaus ZEN matters because ZEN is a combined DNSBL used for email filtering, so listed sending IPs can be rejected or degraded by receivers until the underlying abuse condition is fixed and the listing is cleared[1][2]. For this finding, the authoritative remediation is to identify the specific Spamhaus zone and follow Spamhaus’s own resolution steps, then request removal after correcting the root cause[1][2][4].
1. Confirm the exact Spamhaus listing and scope using Spamhaus’s IP and Domain Reputation Checker or the IP removal flow, because ZEN is a combined list and the resolution depends on the specific sub-list and reason[1][2].
2. Stop any mail or traffic that is causing the listing before requesting removal; Spamhaus explicitly directs you to fix the issue found in the checker and, for IP-based listings, to use the suggested resolution steps[1][4].
3. Fix the mail-server identity and routing settings Spamhaus requires: the HELO domain must resolve to the sending IP, the sending IP must have valid reverse DNS, the reverse DNS must match the HELO domain, and forward-confirmed reverse DNS must resolve back to the sending IP[4].
4. If the IP is shared or controlled by your hosting/provider, open an abuse/remediation ticket with that provider and ask them to correct the listing condition and submit delisting if needed; Spamhaus states that some listings require the ISP/provider to act[9].
5. After the root cause is corrected, use Spamhaus’s removal

Content-Security-Policy header not set
Medium4.0–6.9 · A05 Security Misconfiguration · CWE-1021DetectedConfirmed fixWhere / evidence: HEAD response for the target omitted the Content-Security-Policy response header.
Impact: No CSP means injected scripts (XSS) run without a defence-in-depth backstop.
Why it matters: CSP is a key defence-in-depth control against XSS and data injection; without it, injected scripts run freely.
AI Recommended Fix:- Start with a report-only policy to measure impact, then enforce.
- Define explicit default-src / script-src allow-lists; avoid 'unsafe-inline'.
- Use nonces or hashes for any required inline scripts.
# nginx
add_header Content-Security-Policy "default-src 'self'; object-src 'none'; base-uri 'self'" always;

HTTP-alt port 8080 is internet-reachable
Medium4.0–6.9 · A05 Security Misconfiguration · CWE-668DetectedResearched · citedWhere / evidence: TCP connect to public IP 104.21.57.221:8080 succeeded from an external vantage — HTTP-alt reachable from the internet.
Impact: Port 8080 open to the internet — often exposes an admin panel or internal app server. Should not be publicly reachable.
Why it matters: An internet-reachable HTTP-alt port 8080 violates the **principle of least privilege** and exposes your system to unauthorized access, exploitation of unpatched development services, and malware distribution, as this port is commonly used for HTTP proxies and development servers that often lack security controls[1][2].
### 1. Why it Matters
* **Unauthorized Access & Data Theft:** An open port provides a direct entry point for attackers to bypass firewalls, potentially leading to unauthorized access to sensitive information or system compromise[1][3].
* **Exploitation of Vulnerable Service

### 1. Why it Matters
* **Unauthorized Access & Data Theft:** An open port provides a direct entry point for attackers to bypass firewalls, potentially leading to unauthorized access to sensitive information or system compromise[1][3].
* **Exploitation of Vulnerable Services:** Port 8080 is frequently used for **development, staging, or proxy servers** that often lack security patches, strong authentication, or web application firewalls (WAF), making them easy targets for SQL injection, XSS, and other attacks[1][2].
* **Malware & DDoS Launchpad:** If left unrestricted, attackers can exploit vulnerabilities to install malware, perform Distributed Denial of Service (DDoS) attacks, or use the server as a proxy to spread malware[1].
* **Service Discovery:** Open ports allow vulnerability scanners to identify HTTP services on non-standard ports, enabling attackers to perform reconnaissance and dictionary-style guessing to find hidden applications[6].
### 2. Numbered Fix Steps
1. **Restrict Inbound Access via Firewall:** Configure your firewall (e.g., `iptables`, `ufw`, AWS Security Groups, or cloud firewall rules) to **block all inbound TCP traffic to por

Impact: Publicly reachable resource that should not be exposed.
Why it matters: Third-party script injection (Magecart, skimmers) is one of the most common ways attacker code reaches end users. Every foreign script is an unaudited dependency that runs with full page privileges.
AI Recommended Fix:- Audit all third-party scripts and remove or self-host those that aren't strictly necessary.
- For scripts you must keep, add a Subresource Integrity (SRI) hash: integrity='sha384-...' crossorigin='anonymous'.
- Implement a strict Content-Security-Policy script-src allowlist that blocks unapproved origins.
- Monitor for new foreign scripts using regular crawl scans.

dns_dmarc_weak
Low0.1–3.9 · A05 Security Misconfiguration · CWE-200DetectedConfirmed fixWhere / evidence: DMARC policy is p=none — spoofed mail is monitored but not rejected. Upgrade to p=quarantine or p=reject to block spoofed mail
Impact: Publicly reachable resource that should not be exposed.
Why it matters: p=none provides monitoring data but no enforcement — spoofed messages from your domain still land in inboxes.
AI Recommended Fix:- Review rua/ruf aggregate reports to ensure all legitimate senders pass SPF and DKIM.
- Escalate policy to p=quarantine, then p=reject once confident legitimate mail is covered.

Impact: Publicly reachable resource that should not be exposed.
Why it matters: Why it matters: `~all` is a softfail policy, which means messages from unauthorized senders are not rejected outright and may still be accepted for delivery, typically with a warning or spam marking; `-all` is the stricter hardfail policy that tells receivers to reject unauthorized mail.[1][2]
1. Audit every legitimate email sender for the domain, including mail servers, SaaS senders, and third-party services, so the SPF record authorizes all real sending sources before enforcement is tightened.[2][3]

3. Verify the updated SPF record is syntactically valid and published in DNS, then test that all legitimate mail still passes SPF after the change.[2][3]
4. If the domain is still in transition and cannot safely reject unknown senders yet, keep `~all` only temporarily; do not leave it in place once the sender set is known and stable.[1][3]
